  1. 21. Graphene FET terahertz detectors on flexible substrates

    Författare :Xinxin Yang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensors; THz detectors; flexible electronics; 2D materials; Graphene; field-effect transistors; plastic substrates.;

    Sammanfattning : Terahertz (THz) science and technology have developed rapidly over the past decades, extending the THz application areas from spectroscopy and earth and space sciences to communications, biomedicine and security sensing. Many of these emerging applications require shape-conforming, light-weight and low-cost detectors rather than existing solid-state detection technology. LÄS MER

  3. 22. Modelling of Radiographic Testing to Derive a Detection Positioning and Sizing Algorithm for Pore Defects

    Författare :Erik Lindgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : When laser welding light weight materials, e.g. aluminium and titanium based alloys, small sub-millimeter pore defects occasionally forms. Due to their small sizes, less than some 0. LÄS MER

  4. 23. Synthesis and Characterization of Acceptor Polymers for All-Polymer Solar Cells and Photodetectors

    Författare :Zhaojun Li; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; morphology; all polymer solar cells; all polymer photodetectors; conjugated polymers; charge recombination;

    Sammanfattning : The development of polymer semiconductors has become an important topic due to its advantages of low cost, easy fabrication, light weight, and capability to fabricate flexible large-area devices. For example, as the need for new clean energy sources is increasing, polymer solar cells (PSCs) are being developed rapidly and becoming a promising alternative to silicon solar cells. LÄS MER

  5. 24. Data-driven Modeling of Robotic Manipulators – Efficiency Aspects

    Författare :Stefanie Zimmermann; Martin Enqvist; Svante Gunnarsson; Cristian Rojas; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Robotic manipulators are used for industrial automation and play an important role in manufacturing industry. Increasing performance requirements such as high operating speed and motion accuracy conflict with demands on heavy pay-loads and light-weight design with reduced structural stiffness. LÄS MER

  7. 25. Mechanical anchorage of prestressed CFRP tendons : theory and tests

    Författare :Anders Bennitz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Fibre Reinforced Polymers (FRPs) are slowly becoming important materials to consider also for a structural engineer. They are light-weight, insensitive to corrosion and have highly modifiable mechanical properties. LÄS MER
